COMBINATION LOADER AND UNLOADER.

Specification of Letters Patent.

Patented July 13,1920.

Original application filed October 20, 1916, Serial No. 126,739. Divided and this application fiIed August 22, 1918. Serial No. 250,997.

To all whom it may concern:

Be it known that I, Crmnnns A. Pnnrnor, a citizen of the United States, residing at Sunbury, in the county of Delaware and tate of Ohio, have invented a new and useful Combination Loader and Unloader, of which the following is a specification.

This application discloses and claims matter which was ruled to be divisible from what is claimed in my prior application No. 126,739, filed Oct. 20, 1916, that application having now matured into Patent No. 1,218,580, granted 011 the 6th day of March, 1917. The patent alluded to covers sundry improvements in a reciprocating feeder per 86, whereas this present application is based on an elevator comprising a reciprocating feeder and an endless conveyor, as shown and described in my said patent, but not claimed therein.

The invention aims to provide novel connections between a right-line feeder and an inclined conveyor, whereby these instrumentalities may be operated from a single source of power, and to combine the feeder and the conveyor in a novel way, to produce a machine which is more compact and efiicient than those which have preceded it.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description procoeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herewith disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings,

Figure 1 is a transverse sectional view showing an automatic loader embodying the improvements hereinafter described, certain parts appearing in elevation;

Fig. 2 is an end elevation showing the recoiver and attendant mechanisms;

Fig. 3 is a cross section taken through the receiver on the line 3-3 of Fig. 6;

Fig. 4 is a side elevation of the receiver;

Fig. 5 is a longitudinal section of the receiver; and

Fig. 6 is a top plan of the receiver.

on adjacent cross ties 2 are inclined deflectors 4-. WVhen the material is dumped out 1 of a car, the deflectors direct the material be tween the cross ties 2. Between the cross ties 2, a channel 5 is formed in the road bed 1, transversely of the rails 3, the channel 5 communicating with a pit 6 formed in the road bed 1 on one side of the track rails 3. Beyond the pit (3 and to one side of the track 33 is a support 7.

A receiver is located between the cross ties 2, and the material dumped from a car is directed by the deflectors 4 into the receiver. The receiver is a composite structure, and its construction will now be set forth.

j The receiver embodies a bed frame includ- V ing a pair of side bars 8 preferably in the form of channels, the side bars 8 being connected by upwardly inclined crossed braces 9 and by transverse braces 10. The side bars 8 carry bolts 11 supporting hangers 12 which may be connected by the rails 3. Any other desired means, however may be employed for holding the channels or side bars 8 in place. vSecured to the side bars 8 are uprights 1 1 sustained from the side bars by means of braces 15. Attached to the uprights 1d are side plates 16. Guide strips 17 are attached to the inner faces of the side plates"16 by means of securing elements 18. The slots 19 in the side plates 16 through which the securing elements 18 pass preferably are elongated vertically as clearly indicated in Fig. 4 so that the guide strips 1'? be adjusted vertically.

Connected with the side plates 16 near to their rear ends are angle bars 20 to which is secured a forwardly and downwardly inclined wall 21 supporting a foot 22 held in place on the wall 21 by securing elements 23. The slots 24 in the foot 22 through which the securing elements 23 pass are elongated vertically, so as to permit an adjustment of the foot 22.

The receiver above alluded to includes a reciprocating feeder, embodying a base plate 25 in slidable cooperation with the guide strips 17 which are secured to the side plates 16. Attached by means of a securing element 29 to the forward end of the base plate 25 is a bar 26 supporting a removable lip 2'7 held in place by a securing device'28, the

in the upper end of the conveyer frame. 51.

construction being such that the lip may be 7 renewed readily when worn. Extended longitudinally of the base plate 25 and secured thereto are'wear strips 30 which bear immediately upon the lower edges of the guide strips 17. Securedto the rear end of the member 25 is a plate 31 held. inplace by se- "curing elements 32,. the plate 31 operating beneath the lower end of the inclined foot 22.

At this place it may be noted that thefoot 22 is so mounted on the wall 21 that the foot maybe raised and lowered to cotiperate with theplate 81, itbeing possible to adjust the guide strips 17 vertically so that they will.

coiiperate with the wear strips30, and all of these elements, may be detached and replaced when worn. V 7

Fixed to and depending from the base plate 25 of the feeder are angle members 83, the vertical flanges of which liebetween rollers 34, the horizontal flanges of which constitute tracks cofiiperating with the rollers as shown best in Fig. 3. The rollers 3 1 are carried by axles 35 supported in the channels or side bars 8. It will now be clear that when the feeder comprising theplate 25 and attendant parts is reciprocated, the. plate slides to and, fro on the rollers 3 1, the rollers constituting an anti-frictional mounting for the plate.

Attached to the base plate 25 of the feederare laterallyoffset brackets 36 carrying pins 37 which are mounted upon the base plate 25 of the feeder, asindicated at 38 in Fig. 3. The pins 37 supportpivotally, the rear ends of pitmen 39 united by adjustable connections 4:0 with eyes 11 pivoted on wristpins' l2 carried by cranks 4L3 constituting a part of a shaft 4 1 journaled in bearings 15 secured to the forward ends ofthe channels or side bars 8. Fixed to naled for rotation in the lower end of the conveyor frame 51 (which projects into the pit6) is a shaft 5 1-. A shaft 55 is journaled Trainedabout the shafts 54 and 55 and operatively connected therewith a belt conveyer 56 adapted to operate in the pitiG. Journaled in the conveyer frame 51 intermediate its ends is av shaft 57 connected by means of a chain 64: with the sprocket wheel 46 onthe shaft 414 whereby the feeder plate 2.5 is actuated. t sprocket chain 58 forms he shaft 1a is a sprocket wheel at). A downwardly inclined wheel 60 connected by means of asprocket' chain 61 with the shaft 62 of amotor 63 mounted on the support 7 in practical operation, the 'niaterial dumped from a car is received by the deflectors 1 and is directed between the side plates 16 of. the receiver.. When the feed plate 25 is reciprocated, the material is advanced into the chute d7, owing to the fact that the material tends to bank up on the inclined wall 21, and because the tendency of the inclined wall is to coact with the feeder plate 25 in advancing the material. From the chute 41-7, the materlalis received by the belt conveyer 56 and is carried upwardly by the belt conveyer and dumped into the bin d8. 1

When the motor 63 is operated,mot1on 1s transmitted to the shaft 57 by the sprocket chainQGl, and from the shaft 57, motion is transmitted'to the shaft 55 and the .belt conveyer 56 by the chain 58. Fronithe shaft 57, motion is transmitted by the sprocket chain '64 .to the sprocket wheel #16 on the shaft 4d and whenthe shaft 44: is rotated, the pitmen 39 will be actuated, the same imparting a sliding movement to the feeder plate 25. through the pins 37.,

One end-of the receiver overhangs the lower end of the conve er 56 and the re-' ceiver discharges downwardly, directly into the conveyor. The feeder, embodying the plate 25, has a right-hne movement n a fixed planeQand the pitmen- 39, the crank shaft 11%, the chain 6 1, the shaft 57, the

shafts 5 11, the chain 5S,'and the chain 61,

form a simple but efficient means whereby the feeder and the conveyor 56jmaybe driven from a single source 63 of power. i

i T claim p i In a device of the class described, an approximately horizontal feeder including. a reciprocating.element; a conveyor frame; first shafts journaled at the endsjof the frame; a bucket conveyer carried'by the shafts and extended beneath ,thedelivery end of the feeder; a drive shaftjournaled in the frame. between the first shafts; means for operatively connecting, the drive shaft with the reciprocating element of the feeder independently of the bucket conveyer; a belt connection between thedrive shaft and one of the first shafts, thebelt connection being independcnt of the bucket conveyer; and means for operating the drive shaft.

In testimony that claim the foregoing as own, I have hereto affixed my signature in the presence of two witnesses.
